RESUMEN

Aims: The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS)-study aimed to quantify the prevalence of cardiovascular risk factors (CVRF) and cardiovascular disease (CVD) in German childhood cancer survivors (CCS). Methods and results: In the CVSS-study (NCT02181049), 1002 CCS (age range 23-48 years) diagnosed with neoplasia prior to 15 years of age between 1980 and 1990 prospectively underwent a systematic, standardized clinical and laboratory cardiovascular screening, identical to the population-based Gutenberg Health Study (GHS) cohort. For 951 individuals, prevalences of CVRF and CVD were primarily compared to the GHS sample and to two further German population-based cohorts. Using log-binomial regression models, an increased risk for occurrence of arterial hypertension [relative risk (RR) 1.38, 95% confidence interval (95% CI 1.21-1.57)] and dyslipidaemia [RR 1.26 (95% CI 1.12-1.42)] was found. This indicates a premature occurrence compared to the general population of approximately 6 and 8 years, respectively [rate advancement period estimator, RAPhypertension 5.75 (95% CI 3.5-8.0) and RAPdyslipidaemia 8.16 (95% CI 4.4-11.9)]. Overall, no differences were observed for obesity and diabetes. Overt CVD was present in 4.5% (95% CI 3.0-6.6%) of CCS [RR 1.89 (95% CI 1.34-2.66), RAPCVD 7.9 (95% CI 4.1-11.7)], of which the most frequent entities were congestive heart failure and venous thromboembolism. Prevalences of CVRF and CVD increased with age without reaching a plateau over time. Conclusion: This large CCS screening examination revealed consistently in comparison to three population samples a considerably increased risk for premature CVD. The findings in these young adult CCS indicate a high burden of cardiovascular morbidity and mortality in the long term. Clinicaltrials. gov-Nr: NCT02181049.

RESUMEN

Essentials The increase of cancer survival remains curtailed by cardiovascular mortality. We studied a large range of inflammatory and coagulation biomarkers in long-term cancer survivors. Cancer history has an important impact on mortality independent of cardiovascular risk factors. Fibrinogen and von Willebrand factor are potential biomarkers in survivors of increased mortality. SUMMARY: Background The advances in cancer treatment and detection of early cancer have resulted in a steady increase in the number of of cancer survivors over the years. However, because of the long-term toxic effects of chemotherapy and radiotherapy, the incidence of cardiovascular disease (CVD) is increasing in survivors. Objectives To investigate traditional cardiovascular risk factors (CVRFs), inflammation and the coagulation profile in long-term cancer survivors (cancer diagnosis ≥ 5 years) from a large adult population-based study sample. Methods The presence of cardiovascular risk factors (CVRFs) and laboratory markers were compared in individuals with (n = 723) and without (n = 13626) a long-term history of cancer from the Gutenberg Health Study. Data on coagulation factors, D-dimer and von Willebrand factor (VWF) activity were available for 4974 individuals (n = 244 cancer survivors). Results In multivariable regression models, a history of cancer was, independently of CVRFs and CVD, associated with higher fibrinogen levels (ß 6.99, 95% confidence interval [CI] 1.16-12.8), VWF activity (ß 5.08, 95% CI 0.02-10.1), and antithrombin activity (ß 1.85, 95% CI 0.44-3.27). Cancer survivors with CVD showed notably higher VWF activity than individuals with CVD without a history of cancer, with a difference in the means of 23.0 (7.9-38.1). Multivariate Cox regression analysis, adjusted for CVRFs, confirmed that a long-term history of cancer is associated with a 72% higher mortality. Increased mortality in cancer survivors was dependent on fibrinogen level and VWF activity level. Conclusion Cancer survivors showed a worse inflammation and coagulation profile than individuals without a history of cancer. Overall mortality in long-term cancer survivors was increased independently of traditional CVRFs. These results underline the need to further investigate plasma biomarkers as complementary cardiovascular risk predictors in cancer survivors.

RESUMEN

BACKGROUND: There are detailed reviews about different recruitment strategies, but not with regard to differences between recruitment of hospital-based versus office-based physicians. Within this study, the two different recruitment schemes are compared. Advantages and disadvantages of different ways of recruitment in registry-based studies are discussed. METHODS: In a cross-sectional cancer-registry-based study, long-term melanoma patients were contacted by dermatologists rather than directly by the registry on the basis of the legal situation. Logistic regression models and generalized estimating equations were used to assess effects of various patient and physician characteristics on participation and data quality. Especially differences between hospital-based versus office-based dermatologists are evaluated. RESULTS: Seventy two out of 112 contacted dermatologists took part in the study (64.3%). The cooperation proportion was 52.2% (689 participants/1320 contacted patients). Participants and non-participants differed regarding age and sex, but not regarding other social demographic factors and cancer stage. We did not observe a difference in patient participation between hospital-based versus office-based dermatologists (OR 1.08 [CI 0.84-1.39]; p = 0.57). However, medical data provided by the cancer registry were better for participants registered and recruited by hospitals. CONCLUSIONS: In cohort studies with epidemiological cancer registries, recruitment via physicians has potential disadvantages and is more complex. If this indirect way of contact is mandatory, we recommend recruitment procedures including hospital-based rather than office-based physicians. However, physician characteristics were not associated with outcome.

RESUMEN

PURPOSE: Multimodal therapies affect the quality of life (QoL) of patients with primary breast cancer (PBC). The objectives of this prospective study were to explore the changes in QoL from diagnosis to conclusion of adjuvant therapy and to identify predictive factors of QoL. METHODS: Before surgery (t1), before onset of adjuvant treatment (t2) and after completion of adjuvant chemo- or radiotherapy (t3), patients with PBC (n = 759) completed the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire, Charlson Comorbidity Index, Patient Health Questionnaire and Perceived Involvement in Care Scales. Predictors of the course of global QoL were estimated using multinomial logistic regression. Effect estimates are odds ratios (OR) and their 95% confidence intervals (CIs). RESULTS: Global QoL improved between t1 and t3, while physical functioning, emotional functioning and fatigue deteriorated. QoL before surgery was more often poor in patients <60 years (OR 2.2, 95% CI 1.5-3.1) and in those with comorbid mental illnesses (OR 8.6, CI 5.4-13.7). Forty-seven percentage reported good global QoL both at t1 and at t3. QoL improved in 28%, worsened in 10% and remained poor in 15%. Compared to patients with consistently good global QoL, a course of improving QoL was more often seen in patients who had received a mastectomy and in those with intense fear of treatment before surgery. A course of decreasing QoL was more often found in patients who were treated with chemotherapy. QoL stayed poor in patients with chemotherapy, mastectomy and intense fear. There was no evidence that radiotherapy, progressive disease or perceived involvement impact the course of QoL. CONCLUSIONS: Younger age and comorbid mental illnesses are associated with poor QoL pre-therapeutically. QoL is more likely to stay or become poor in patients who receive chemotherapy.

RESUMEN

BACKGROUND: There is no consensus on the treatment and prognosis of malignant rectal polyps. The aim of the present study was to determine the role of transanal endoscopic microsurgery (TEM) after endoscopic complete polypectomy of malignant rectal adenomas with long-term follow-up. METHODS: Of 105 patients with pT1 rectal carcinoma in 32 patients TEM followed complete endoscopic polypectomy while 73 had primary TEM. Local recurrence (LR), distant metastasis, overall and cancer-specific survival were determined by the Kaplan-Meier method. RESULTS: Median follow-up was 9.1 years. In 32 patients with TEM following complete polypectomy no residual cancer was found. LR occurred in 3/28 (11%) patients with low-risk carcinoma (pT1 G1/2/X, L0/X, R0) and in 1/4 (25%) with high-risk carcinoma (pT1 G3/4 or L1). After primary TEM with complete resection (minimal distance >1 mm) LR occurred in 6/60 (10%) with low-risk carcinoma. After incomplete TEM resection (minimal distance ≤1 mm) LR occurred in 3/8 (38%) patients with low-risk and in 1/5 (20%) patients with high-risk carcinoma. Grading was the only significant risk factor for LR after endoscopic polypectomy followed by TEM (p = 0.002). At all outcomes did not differ between postpolypectomy TEM and primary TEM. CONCLUSIONS: Patients with malignant rectal polyps removed by endoscopic polypectomy have a substantial risk of LR even if TEM of polyp site is cancer free. Risk of LR depends on tumor characteristics. In low-risk carcinoma long-term follow-up is necessary. The high LR rate in patients with high-risk rectal carcinoma restricts the use of TEM alone.

RESUMEN

The aim of the rheumatology network ADAPTHERA ("risk-adapted rheumatology therapy") is to achieve a comprehensive improvement in rheumatology care by coordinating treatment in a regional, trans-sectoral network. Accompanying biomedical research projects, training concepts, and the construction of a rheumatology register (gathering data and biomaterials) should furthermore ensure the stable and sustainable optimisation of care. In the pilot phase (2012-2015) the focus of the ADAPTHERA network, required as a "regional key project" within the framework of the Initiative on Health Economy of Rheinland-Palatinate (RL-P), Germany, was placed on the optimisation of the early diagnosis of rheumatoid arthritis, where it is well-known that there is a significant care deficit.Through the intensive, stable, and coordinated cooperation of all health care partners in the field of rheumatology (registered general practitioners and orthopaedic specialists, registered core rheumatologists as well as the Association of Rheumatology of RL-P) a unique regional, comprehensive offer with verifiable care optimisation has been established in RL-P. The network is supported by outstanding collaboration with the Association of Statutory Health Insurance Physicians and the self-help organisation Rheumatology League.The aims that were established at the start of the project will be achieved by the end of the pilot phase:- significant improvement in the early diagnosis of rheumatoid arthritis (an average of 23.7 days until diagnosis by rheumatologists)- access covering all health insurance (regardless of the particular scheme the patients belong to)- comprehensive (verifiable participation of general practitioners from all over RL-P)- data and biomaterials collection, established as a basis for biomarker research, and a rheumatology register for RL-P.

RESUMEN

PURPOSE: The study examines the association between exposure to current and cumulative night shift work and subclinical parameters of atherosclerosis. METHODS: Participants of a population-based cohort study (the Gutenberg Health Study, N = 15,010) aged 35-64 years were examined at baseline (2007-2012). Investigations included measurements of arterial stiffness, vascular function [reactive hyperaemia (RH) index], and intima media thickness (IMT). Also, a complete job history (including up to 15 periods), occupational exposures, a variety of lifestyle, and dispositional variables were enquired. RESULTS: Night shift work was performed by 1071 out of 8065 currently employed individuals. The strongest association after adjustment for age, sex, job complexity level, being a manager, overtime work, and noise appeared for more than 660 night shifts within the last 10 years and a significantly increased arterial stiffness of 0.33 m/s. This reflects a 4 % flow velocity increase for individuals with more than 660 night shifts compared to non-night workers. Regarding the entire professional life, night shift workers showed a significantly decreased vascular function by -0.054 RH index points by using the same adjustment. IMT values did not differ statistically from non-night workers. Lifestyle and dispositional factors showed an influence on all used subclinical atherosclerosis parameters. CONCLUSIONS: The cross-sectional results demonstrate an association between night work and detrimental changes in the atherosclerotic process. The association is more pronounced with more years in night shift and is partly explained by lifestyle and dispositional factors. Longitudinal analyses are necessary to confirm the results.

RESUMEN

OBJECTIVE: Distressed ('Type D') personality is associated with adverse health outcomes in patients with cardiovascular disease (CVD). While personality traits from the Five-Factor Model are related to cognitive functioning, neither Type D personality nor its underlying traits negative affectivity (NA) and social inhibition (SI) have been investigated regarding cognition. We therefore compared the predictive value of Type D classification and its subcomponents NA and SI on planning performance in individuals with and without CVD. METHODS: Type D personality traits (DS14) were determined in a population-based sample of 4026 participants (including 549 with CVD) aged 40-80years from the Gutenberg Health Study (GHS) and related to planning performance as assessed with the Tower of London task. Current depression and anxiety were controlled as state variables. RESULTS: Type D personality status was negatively associated with planning performance in the CVD patient group only (p<0.001) but had no impact in the non-CVD group (p=0.40). In the overall sample, NA was negatively and SI positively associated with planning performance. No differential effect on planning between groups was found for depression and anxiety. CONCLUSION: While the subcomponents NA and SI in the population-based sample confirm and extend previous research on personality traits and cognition, Type D personality classification in combination with CVD emerged as a risk factor for decreased cognitive functioning, independent of depression and anxiety. These findings implicate the need to early focus on individual differences in cognitive functioning in patients with CVD.

RESUMEN

This article explains some important concepts of screening and early detection. It also discusses under which circumstances screening is useful, who can profit from screening and which persons may be at risk from screening procedures. Before the introduction of a screening program, empirical studies on the effectiveness are necessary to evaluate whether a screening program could be successful.

RESUMEN

PURPOSE: Inflammatory breast cancer (IBC) represents a rare and aggressive form of cancer with negative prognosis and high rate of recurrence. The purpose of this retrospective multi-center study was to evaluate the effect of IBC on overall and disease-free survival. Furthermore we analyzed the influence of hormone and Her2 receptor expression on inflammatory breast cancer cells on the clinical outcome of patients. METHODS: This retrospective German multi-center study included 11,780 patients with primary breast cancer recruited from 1992 to 2008. In this sub-group analysis we focused on 70 patients with IBC. RESULTS: Despite the relatively small sample size, we could confirm the aggressiveness of inflammatory breast cancer and the different clinical behavior of IBC subtypes. It could be demonstrated that the lack of expression of hormone receptors on tumor cells is associated with a more aggressive clinical course and decreased overall and disease-free survival. Higher incidence of Her2 overexpression, that is typically associated with poor prognostic outcome among women with non-IBC tumors, seems however to have no prognostic significance. CONCLUSIONS: This BRENDA sub-group analysis, on a German cohort of breast cancer patients confirmed the negative outcome of IBC and the different clinical behavior of IBC subtypes. The best management of IBC requires intensive coordination and cooperation between various clinical disciplines involved in the treatment of IBC patients. Moreover there is a need to identify IBC-specific targeted therapies to improve the curing prospects of this subtype of cancer.

RESUMEN

The aim of this cohort study was to assess the risk of developing cancer, specifically leukaemia, tumours of the central nervous system and lymphoma, before the age of 15 years in children previously exposed to computed tomography (CT) in Germany. Data for children with at least one CT between 1980 and 2010 were abstracted from 20 hospitals. Cancer cases occurring between 1980 and 2010 were identified by stochastic linkage with the German Childhood Cancer Registry (GCCR). For all cases and a sample of non-cases, radiology reports were reviewed to assess the underlying medical conditions at time of the CT. Cases were only included if diagnosis occurred at least 2 years after the first CT and no signs of cancer were recorded in the radiology reports. Standardised incidence ratios (SIR) using incidence rates from the general population were estimated. The cohort included information on 71,073 CT examinations in 44,584 children contributing 161,407 person-years at risk with 46 cases initially identified through linkage with the GCCR. Seven cases had to be excluded due to signs possibly suggestive of cancer at the time of first CT. Overall, more cancer cases were observed (O) than expected (E), but this was mainly driven by unexpected and possibly biased results for lymphomas. For leukaemia, the SIR (SIR = O/E) was 1.72 (95 % CI 0.89-3.01, O = 12), and for CNS tumours, the SIR was 1.35 (95 % CI 0.54-2.78, O = 7). Despite careful examination of the medical information, confounding by indication or reverse causation cannot be ruled out completely and may explain parts of the excess. Furthermore, the CT exposure may have been underestimated as only data from the participating clinics were available. This should be taken into account when interpreting risk estimates.

RESUMEN

INTRODUCTION: It is well accepted that innovation in oncology is transported through randomized clinical trials (CT), furthermore there is some evidence that patients profit from participation in CT. However, especially elderly patients aged >65 usually do not have access to clinical trials; we therefore used an unselected patient cohort to investigate the following questions: (1) Is there a difference in survival parameters between study participants <65 and elderly 65-80 non-participants? (2) Is guideline-adherent adjuvant treatment an equal alternative for elderly patients aged 65-80? MATERIALS AND METHODS: This German retrospective multi-center cohort study included 4,142 patients (study participants <65 and elderly breast cancer patients 65-80) with primary breast cancer recruited from 1992 to 2008 in 17 participating breast cancer centers. RESULTS: Applying the exclusion criteria, we included 960 (23.2%) study participants (PA) <65 and 3,182 (76.8%) elderly >65. Elderly non-participants (NPA) >65 demonstrate a significantly inferior RFS [RFS: HR = 1.67; p < 0.001] and OS [OS: HR = 1.98; p < 0.001] compared to PA <65. Within the elderly group, 1,868 (58.7%) patients received guideline-adherent adjuvant treatment. When comparing guideline conform elderly >65 versus PA <65, we found no significant difference in RFS [RFS: HR = 1.17; p = 0.218] and OS [OS: HR = 1.34; p = 0.054]. In contrast, non-guideline-adherent elderly demonstrated significantly inferior survival parameters [RFS: HR = 2.06; p < 0.001] [OS: HR = 2.50; p < 0.001] compared to <65 PA. CONCLUSION: Guideline-adherent adjuvant treatment seems to be an equivalent option for elderly breast cancer patients. There is a strong association between guideline adherence and improved outcome parameters in elderly breast cancer patients.

RESUMEN

OBJECTIVES: Estimation of the attributable risk for fatal diseases by combining two different data sources. METHODS: We derive a method to estimate the attributable risks of different risk factors by combining general mortality risks with up-to-date prevalences of the risk factors using estimates from a risk prediction model and cross-sectional data of a cohort study. Partial attributable risks have been used to illustrate the proportions of the different risk factors for the attributable risk. In addition we derive standard errors for the attributable risk based on the Taylor series expansion. Since the data of our cohort study was sampled with the same size in each 10 years age stratum which does not reflect the age-structure of the general population, the attributable risk and its standard errors are calculated using an approach that allows the weighting of the data according to population proportions of age. The formula for the standard errors has been evaluated using bootstrap-techniques. RESULTS: We successfully implemented the method for the estimation of the attributable risk and its standard errors by integrating risk information using data of the HeartScore Germany and cross-sectional data emerging from the Gutenberg Health Study. The attributable risk can now be calculated without using the information of the overall disease rate. The bootstrap method shows, that the formula for the standard errors is useful. CONCLUSION: Our method allows for the combination of different data sources in order to estimate attributable risks and our formula for the standard errors seems to yield a good approximation. But the validity of our method highly depends on the validity of the underlying data sources.

RESUMEN

AIM: Adjuvant chemotherapy has changed dramatically in the last decades. Anthracycline-/Taxane-based and dose-dense chemotherapy regimens improved survival in node positive breast cancer. This study tries to answer the following questions: METHODS: This is a German multi-centre (17 participating hospitals all certified as breast cancer centres) retrospective cohort study. We included patients that received CMF-like (CMF) (n=1308), Anthracycline-based (A) (1046), Anthracycline-Taxane-based (AT) (1110) and dose-dense chemotherapy (DD) (213) into this analysis. RESULTS: In case of N0 and 1-3 pos LN we did not observe statistically significant differences in overall (OS) and disease-free survival (DFS) between CMF/A/AT and (for 1-3 pos LN) DD. In the group of 4-10 pos LN we observe an improvement by the use of AT-based chemotherapy, which cannot further be improved by DD chemotherapy. However in the highest risk group, defined as ⩾11 pos LN, we observed a statistically significant improvement in survival by the use of DD chemotherapy. Also a statistically slightly non-significant trend towards improvement of survival parameters by the use of DD compared to AT chemotherapy could be observed. Only for G3 subtypes we could observe a survival benefit for DD. These results remain consistent after exclusion of non-guideline adherent patients (surgery, radiotherapy and endocrine therapy) in order to reduce the bias of guideline violations in other adjuvant treatment modalities. CONCLUSION: DD chemotherapy is associated with improved survival parameters in patients with ⩾11 positive LN.

RESUMEN

BACKGROUND: The aim of this study was to clarify whether the lymph node ratio (LNR) is superior to the updated TNM classification regarding the prognosis of stage III rectal cancer patients who have not undergone neoadjuvant therapy. The TNM system is based on the absolute number of lymph nodes involved, and the LNR takes into account involved and examined nodes. METHODS: In 237 patients with stage III rectal cancer, we evaluated prognostic factors for 5-year overall survival (OS), disease-free survival (DFS), and risk of distant metastases (DM) using the Kaplan-Meier method, with patients divided based on adequate versus inadequate lymph node dissection (≥12 vs. <12 lymph nodes examined). The updated TNM divides patients into four groups (1, 2-3, 4-6, and ≥7 involved nodes), while LNR divides patients into quartiles. Multivariate Cox regression analyses were performed. RESULTS: Among patients with adequate lymph node dissection, the distributions within the two systems were in agreement in 141/178 (79.2 %, kappa 0.721), and the predictive values for OS, DFS, and DM were similar. In patients with inadequate lymph node dissection, the classifications of both systems were concordant in only 13/59 (22 %, kappa 0.021). The pN system significantly under-staged patients, while the LNR classification was a better predictor of OS, DFS, and DM. CONCLUSIONS: In patients with adequate lymph node dissection, LNR staging does not add substantial information to the predictions of updated TNM lymph node staging. However, in patients with inadequate lymph node harvesting, the LNR compensates for the under-staging of the TNM classification and provides a better estimation of prognosis than the updated TNM system.

RESUMEN

BACKGROUND: This prospective study evaluated the relationship between arthralgia and compliance during the first year of adjuvant anastrozole therapy in postmenopausal women with hormone receptor-positive early breast cancer. PATIENTS AND METHODS: COMPliance and Arthralgia in Clinical Therapy (COMPACT) was an open-label, multicenter, noninterventional study conducted in Germany. Patients had started adjuvant anastrozole 3-6 months before the study start. The primary end points were arthralgia, compliance, and the relationship between compliance and arthralgia, assessed at specific time points. RESULTS: Overall, 1916 patients received upfront anastrozole. Mean arthralgia scores were increased from baseline at each visit up to 9 months. Compliance with anastrozole therapy gradually decreased over time from baseline to 9 months (P<0.001). At 9 months, investigators estimated that >95% of patients were compliant versus patient reports of <70%. There was a significant association between arthralgia mean scores and noncompliance at 6 months (P<0.0001), 9 months (P<0.0001), and overall (P<0.0001). Over time, new events or impairment of existing arthralgias were reported in 14% (3 months), 11% (6 months), and 9% (9 months) of patients. CONCLUSION: Arthralgia is important in the clinical management of women with early breast cancer and may contribute to noncompliance and clinical outcomes.

RESUMEN

In 2007, the German Cancer Aid started a program to promote epidemiological research with data from cancer registries. Within this program, ten projects with various epidemiological research questions were funded. The program was a major boost for the use of data from population-based cancer registries and was an important milestone for cancer epidemiology in Germany.

RESUMEN

OBJECTIVES: To test the vascular depression hypothesis in the general population, we analyzed the association between current depression, medical history of depression, cognitive and somatic depressive symptom dimensions and measures of atherosclerosis [intima-media thickness (IMT) and carotid plaques]. METHOD: We included a representative sample of 5000 participants from the Gutenberg Health Study (GHS). Depression was assessed by the nine-item Patient Health Questionnaire (PHQ-9), and IMT and carotid plaques were measured at both common carotid arteries using an edge detection system. Regression analyses were performed separately for participants with and without cardiovascular disease, adjusting for medical history, cardiovascular risk factors and psychotropic medication. RESULTS: Contrary to hypotheses, we found no increased IMT for somatic symptoms of depression; the same was true for depression and cognitive symptoms in the fully adjusted model. Only a moderate relationship between medical history of depression and the presence of atherosclerotic plaques was maintained after correction. CONCLUSIONS: The relationship between depression and atherosclerosis may be more complex than previously assumed. Although the vascular depression hypothesis was not supported, our results support the hypothesis that lasting depression leads to arteriosclerosis.
